4 is the handles serving the purpose of row locks when used as a boat, and through which the lashings may be passed and sen 100 lines in Fig. 3 show the framing of light wood which forms the bows or ends of the boat the inside space being filled in with` cork.` The two sides are joined or fastened together by strap hinges made of girth web. 105 In order to construct the machine, we first make a `strong framing of rat-an, or any suitable material, as shown in Figs. 5 and 6,V and of any required length and breadth; at

'the top bottom, and each end, a double thick- 110 ness of ratan is used. The framework at each intersection being securely and firmly fastened together by lashings of small cord the next process is to put the layers of cork in their proper places the outer layers being secured between the horizontal braces, and occupying two spaces between the vertical bracings extending each way the same dis tance as the other layer. The whole is then covered with strong heavy canvas which is secured at each intersection of the framing, by copper rivets or nails. The canvas covering the air tube d, in order to retain it in its Vplace and protect it from injury by chafing, &c.

A stop cock is attached to the tube; allowing the tube to be filled with air and preventing it-s escape when once lled. The framing of the ends are .made to resemble somewhat the bows of a boat .in shape are also covered in a similar manner with canvas, and hinged to the sides in any suitable manner. The two sides are joined or fastened together with girth web, forming a common strap hinge which enables the machine to lie lat or fold together the part which forms the inside of the boat is lined with india rubber cloth making the boat waterproof. The tube of india rubber cloth is next placed over the joint, its use is to retain the bed or mattress in its place and also to expel any water that may lash into the boatit can, however, be dispensed with without detriment to the successful working of the other parts of the apparatus. half of the'bows, as shown in Fig. 3, is covered with canvas, said canvas being loose at the part containing the eyelets; a canvas flap of similar shape and construction is fastened to the opposite side of the boat; the cord for lashing and holding the parts together passes through these eyelets.

I do not confine myself to the precise arrangement as herein set forth nor the materials mentioned, as it may be necessary to modify the same to suit circumstances, 'as the same may be done without affecting the principle or mode of action.

yOne- In case it should be necessary to convert the machine into a boat, all that you will have to do, will be to turn up the sides, put the bows in their places, draw the cords tightly, and fasten them to the knobs; next draw the apron of india rubber cloth together, and secure the cords to the knobs. The boat is then ready for launching. Should it be preferred to construct a raft a number of the boats may be lashed together` (the diagram, F ig. 7, shows a very suitable arrangement). In order to render the raft stiif oars or any suitable light spars may be lashed transversely as shown in the diagram.y The mattress may be left in the boat, or not as the passenger chooses, being properly secured in its place by means of hooks and loops there is no danger of its shifting, and if more buoyancy is wanted when the boat in the surf would chance to lill with water air tight pillows fastened to the bed in the position to sitk on would give more buoyancy to the boat when filled with water.

Having'thus fully described the nature of my invention, kI would state that I do not claim the material of which the boat is con` Structed, nor do I claim a fiexible or fold up boat, as these vare not new, but 1 lVhat I do claim as new' and desire to secure by Letters Patent is- 1. So hinging the bulkheads or bows to ak iiexible boat as that they may be turned down out of the way for stowage in the bunks or births of a vessel, and may be as readily drawn up and laced so as to form a bow, substantially as described.

2. I also claim in combination with the hinged bulkheads or bows, the apron which is drawn up over the joint of the two bulkheads, for the purpose of preventing any water from entering the boat through said joints, in the manner described.
